Abstract
In existing fluid conveying equipment, a motor and a water pump are divided into two parts, consequently, cost is high, the structure is not compact, the size in the axis direction is particularly large, and the situation whether the motor and the water pump are matched or not needs to be considered as well. Therefore, a novel integrated motor water pump structure needs to be provided. An integrated motor water pump comprises a rotor, a stator and a shell. A rotor rotary shaft is arranged on the center line of the cylindrical shell through a bearing, a stator iron core is arranged on the inner wall of the shell, and a stator winding is wound around the stator iron core; and the rotor rotary shaft is of a hollow structure, in other words, a through hole is formed in the center of the rotor rotary shaft, and spiral blades protruding towards the central line of the rotary shaft are arranged at the middle section in the through hole.
Description
Technical field
The present invention relates to fluid conveying common apparatus industry, be specifically related to a kind of integrated electric motor water pump.
Background technology
In existing conveying equipment for fluid substances, motor and water pump are divided into two parts, and the most not only cost is high, the compactest, the most bulky, but also the problem that need to consider whether to mate between motor with water pump；Currently also have tried to unite two into one water pump drive part and water pump body, such as, in the patent of invention of application number 201410015550.0, impeller is directly set on motor shaft by inventor, directly being fixed by the rotor of motor or be integrally provided on impeller, this version is single, it is impossible to replace existing major part water pump, also it is difficult to also by this structure simultaneously for multistage pump, therefore needs to provide a kind of new a kind of integrated electric motor water pump structure.
Summary of the invention
In order to compress the overall volume of existing motor and water pump, and can reach the function of existing major part water pump, reduce cost, the present invention provides a kind of integrated electric motor water pump.
The present invention is achieved by the following technical solution: a kind of integrated electric motor water pump, including, rotor, stator and housing；Described rotor shaft is arranged on cylindrical housings centrage by bearing, and inner walls is provided with stator core, is tied with stator winding in stator core；It is characterized in that, described rotor shaft is hollow structure, is i.e. provided centrally with through hole at rotor shaft, and arranges, in through hole bosom section, the spiral vane that oriented shaft centerline is protruding.
Further, the spiral vane that described rotor shaft through hole bosom section is arranged is multiple coil shape blade.
Further, described rotor shaft through hole is internal stepped, and the internal diameter of through hole bosom section is more than both sides, and described through hole bosom section is provided with single step helical shape blade or multiple coil shape blade.
Further, described stator winding outer layer is provided with epoxy sealing.
Further, described rotor is winding type or is magneto.
Further, described enclosure interior is provided with cooling line, and described cooling line extends to housing outer rim from housing end face；And on housing end face, it is provided with cooling liquid inlet and outlet.
The present invention a kind of integrated electric motor water pump has the advantages that the spiral vane by original single pump is integrated into the inside of motor rotor shaft, achieve water pump drive part and water pump body unites two into one, save volume when original motor and water pump separates, owing to the spiral vane of pump is integrated in inside motor rotor shaft, instead of the structure of existing water pump axis, increase effective cross sectional area, simultaneously, can be as required, set different helical blade structure, it is achieved the feature of the major part pump such as existing axial-flow pump, centrifugal pump；Multiple coil shape blade can also be set simultaneously, reach the effect of multistage pump.
